Saudi Aramco's Khurais central processing plant has improved propane recovery from its gas train following performance analysis that relied on Lean Six Sigma tools. The Khurais producing department adopted the methodology, traditionally employed as a process-improvement tool throughout such non-process engineering activities as inven-tory management, transportation, and marketing, to address lower propane content in Khurais NGLs.The methodology strictly follows the framework "define, measure, analyze, improve, and control" (DMA1C; see accompanying explanation, p. 106). The department defined the problem through statistical analysis of the current performance and quantification of the propane losses.
